Application filed. November 80, 1906. Serial No.. 345.704.

To all. whom 'it may concern:

Be it known that I, FREDERICK Q. CRE- GIER, `a 'citizen of the United States, anda resident of Chicago, in the county of Cook` and State of Illinois, have invented certain full, clear, and exact specification.

armor for pneumatic tires, and more es ecially for the tires ot .automobiles and ot er very heavy and powerful traction vehicles,

4and which before my invention so far as used with any degree of success has consisted of a leather cover for the tire liavinv` therein at intervals rivets, the outer heads of which are of greater area than are commonly em.- ployed.

The object of my invention is anarnior for pneumatic tires which will entirely isolate the tire from contact with nails, glass and other sharp substances tendinsor to out, penetrate, injure or deface the tire and cause it to collapse or reduce its efficiency and the ivearingqualities of which at the saine time,

will roniote traction without substantially or o Jectioiiably reducing,r the resiliency of the inflated tire.

A further object of my invention is to prol may be quickly removed an'd replaced by a perfect piece and to have the armor of such form that it will cooperate with the fastening devices therefor to secure it upon the tire in such a manner that its accidental removal is prevented, While at the saine time the flexibility' and yielding of the armor to obstructions will be promoted.

With these ends in view, my invention consists in certain features of novelty in the construction, combination and arrangement of parts, by which the said objects and.cer tain other objects hereinafter appearing are attained, all as fully described with reference.

to the accompanying drawings, and more particularly. pointed out in the claims.

' ln the said drawings: Figure l1 illustrates a side elevation .of a wheel for an automobile or other'traction vehicle provided With'' pneumatic tire and .an armor embodying my invention. section through the tire, .the clencher .and vthe Fig. 2 is an enlarged transverse.' i

rim with one of the sections of the armor and a detail portionof one of the spokes shown in side elevation. Fig. 3 is a detailed sideralevation of the .armor in its position .on the .tine This invention relates .to improvements in and particularlyT showing a modification in the form of theends of the sections of the armor and the means by which 4they are secured to the tire. Fig. 4 a detailed' transfA verse section through yone of the armor plates shown in Fig. .8 in its operative 'osition upon the tire and showin(T a means .by ferrule thereof 'mayrbe ermanently secured to the armor section. 'ig. 5 a perspective view of one of the ferrules. 1

Similar characters of reference indicate the saine drawing.

The hub 6, spokes 7 and rim 8 of the wheel shown in Fig. 1 is of the usual construction to which the pneumatic tire 9 is secured in the usual manner, which tireniay be a clenche'ltire secured vto the ri'in in the usual manner, as shown, or which may be of anyI other form of pneumatic tire. commonly employed and secured thereto by any means adapted for that purpose, and furthermore w i pneumatic tire shown is a double tube, it may also be a single tube tire for the style of the tire is immaterial for the purpose of my invention. y

The clenching devices for the tires shown in the drawings are composed of the usual rings 10-,10 ring l1 and bolts 12, but as before stated, suoli a particular structure of pneumatic tire is n ot essential to my invenF which the.

parts in the several figures of thel ile the tion which relates only to the armor and may be further secured to the tire againstv a iieXible connection permitting one or more of said'sections `to yield independently of other sections on striking `an obstruction, and which will eectually prevent pointed V and sharp substances from penetrating therethrough to the tire, and at the same time a'ord better traction than the tread of the tire itself. To these j ends the armor sections 13 are preferably composed of Wood steamed and bent to form, as shown inv the drawing, and of such form and length as to closely embrace" the periphery of the tire when' inHated at points inwardly of the Wheel and beyond the greatest diameter of the tire, as shown in Fig.

. @An important advantage is gained by steaming and bending the sections to form,

l, in that thereby the grain of the wood, as in dicated. 'in Fig. 2, is caused to extend length- Wise of each section, with theresult that their strength and resistance to Wear is thereby best promoted.

Each section 13, as shown in Fig. 2, is provided towards both df its free ends with perforations 14, the perforations of the one section registeringwith those of the other sections adjacent thereto, and providing a means by which all of the sections of a coml plete armor may be strun 'upon a--iiesiible connection such for examp e as a rope, but preferabl a Wire cable 15.

Instea of perforating these sections the free ends of the sections may be tapered and have 'secured thereon ferrules 16,. each of which is provided With lugs 17 having perforations 18, as shown in Figs. 3, 4 and 5 throu h which the cable 15 may be passed for holding thesections together and so they may yield the one independently ofthe other.

Ferrules may be riveted'to the sections but in practice are preferably secured thereto by providing them with one or more projections 19, which maybe bent into the sections as shown in Fig. 4.

' The several sections preferably'ha've their o posing side edges formed on lines radial to t e axis of the wheel upon which the -armor is used so that they will lie close enough to gether to prevent dirt and other foreign substances entering between them and yet any one or more of them be movable inwardly upon adjacentrsections with sufficient freedom'to revent any substantial reductionl in the resilliency of the tire at any time, and

' also to enable the tire to yield to obstructions and ride over them without being punctured, cut or otherwise injured. In

other Words there should be such a number of these sections in the armor having such freedom of movement, ,the one upon the other,4 that the resiliency of the tire will be maintained when passing over obstructions both great and small and yet that in yield'- itself will -not be injured.

The several armor sections are preferably swell and tighten the sections 'against each 'other.

To obtain the best results both as to the resiliency and exclusion of foreign substances liable to puncture and otherwise injure the rubber tire,`such for example as by pointed tacks; nails and the sharp edges of pieces ofmetal and glass, the sections should be loose any possibility-of accidental detachment by .ingto the pressure `of the sections, the tire enough to move freely upon each other to give the greatest possible resiliency to both the armor and the tire and yet tight enough to prevent such substances from passing between the sections of the armor and the tire.

.So far as my invention includes a sectional armor the sections of which are composed of Wood yieldingly connected together and secured to the tire against accidental detachment, my invention is not limited to the particular form of sections shown inthe drawings nor to the means by which they maintain themselves or are maintained from accidental detachment therefrom.

Having described my invention, what l claim and desire to secure by Letters Patent 1s,

1. The combination with a pneumatic tire of an armor comprising a series of sec-v tions of bent W`ood .conforming to the curvature of the tread of the tire and extending to a point inwardly beyond the greater diameter of the tire and clamping the tire in such a'manner as to maintain them in their operative position thereon, substantially as described. 2. The combination with a tire of an armor comprising a series of bent Wood sec-N tions curved to conform to the tread of the tire, 'the grain of which sections extends lengthwise thereof and flexible means connecting said sections and maintaining the armor against accidental displacement from the tire, substantially as described.

3; The combination with a pneumatic tire of an armor comprising a series of permanently bent wood sections, the inner faces of Whichconform to the. curvature of the tread of the tire and a cable connecting said sections and adapted to maintain the armor against accidentaldetachmen't from theA tire, substantially as described.

4. The combination with a pneumatic los tire of an armor comprising a series of Wood sections arranged thereon, and having uninterrupted sides adjacent each other formed on lines radial to the axis of the birennd pro' In witness Whereo, -I have hereunto set,l vided witlpperfomtions or eyesyand a. feximy `hand and nfxed my seal, this 27th, day ble Cable passing through said eyes and vof November A.
